| Abstract: | Mengurangi ketergantungan akan kayu dan emisi formaldehida yang berbahaya menjadi alasan utama dilakukannya studi papan partikel berperekat organik. Pelepah sawit dan kitosan larut air telah diketahui dapat dimanfaatkan sebagai bahan baku papan partikel yang ramah lingkungan. Tujuan penelitian ini adalah menganalisis pengaruh metode kempa three-step press terhadap sifat fisis, mekanis, dan akustik dari papan partikel pelepah sawit berperekat kitosan larut air. Papan partikel disintesis pada variasi suhu 180 oC dan 200 oC. Total waktu pengempaan selama 15 menit dengan breathing stage diletakkan di menit 5 dan menit 10 untuk perlakuan three-step press. Hasil penelitian menunjukkan peletakan fase breathing stage yang semakin mendekati akhir dari total waktu pengempaan meningkatkan sifat fisis dan mekanis papan. Berdasarkan hasil penelitian ini dan merujuk penelitian terdahulu, ada faktor jenis perekat yang berpengaruh pada efektifitas metode three-step press. Secara keseluruhan, variasi suhu 180 oC menghasilkan sifat papan yang lebih baik daripada suhu 200 oC. Pengujian sifat akustik menunjukkan papan yang dikempa dengan metode three-step press termasuk kedalam kategori penyerap suara kelas C menurut standar ISO 11654:1997 dengan nilai NRC sebesar 0,60. Reducing both dependence on wood and harmful formaldehyde emissions are the main reasons for the study of green adhesive particleboard. Palm fronds and water-soluble chitosan have been known to be utilized as raw materials for environmentally friendly particleboard. The purpose of this study was to analyze the effect of the three-step press method on the physical, mechanical, and acoustic properties of water-soluble chitosan-adhesive palm frond particleboard. The particleboard was synthesized at temperature variations of 180 oC and 200 oC. The total pressing time was 15 minutes with the breathing stage placed at 5 minutes and 10 minutes for the three-step press treatment. The results showed that placing the breathing stage closer to the end of the total pressing time improved the physical and mechanical properties of the board. Based on the results of this study and referring to previous research, there is a factor of adhesive type that affects the effectiveness of the three-step press method. Overall, the 180 oC temperature variation produced better board properties than the 200 oC temperature. Tests of acoustic properties show that the board forged with the three-step press method is included in the class C sound-absorbing category according to ISO 11654: 1997 standard with an NRC value of 0.60. |
